SAN FRANCISCO — The San Francisco city attorney has submitted to federal officials the results of an investigation into last year’s Asiana crash, a TV station reported.

The 18-page report to the National Transportation Safety Board — obtained by KGO-TV (http://bit.ly/1b322pq ) — puts some blame on passengers and a flight attendant.

It implies, the station says, that a flight attendant didn’t check to see if everyone’s seatbelts were buckled.

It then says that the cause of death of three passengers was the physical trauma of being ejected from the aircraft because they weren’t buckled in.

The report contradicts the findings of San Mateo Coroner Robert Foucrault, who found that one of those passengers — Ye Meng Yuan — had survived the ejection but was killed after being run over by a fire truck.
